He breakdown of a sample of a chemical compound is represented by the function p(t) 300(0.5)t , where p(t) represents the number

Inessa05 [86]

300 represents the initial amount of the substance, the amount present at t=0.

0.5 is the fraction of substance remaining at the end of each year. The fact that this number is 1/2 indicates the half-life of the substance is 1 year.

Equation Given: <img src="https://tex.z-dn.net/?f=h%28t%29%3D-4.9t%5E%7B2%7D%2B358" id="TexFormula1" title="h(t)=-4.9t^{2}+358"

Vilka [71]

Answer:

At 3.44 seconds, the penny is at a height of 300 meters above the ground.

Step-by-step explanation:

Basically, we have to solve an equation here:

$-4.9t^{2} + 358 = 300$

Hence,

$-4.9t^{2} = 300 - 358$

$t^{2} = \frac{-58}{-4.9}$

$t = 3.44$

Hence, at 3.44 seconds, the penny is at a height of 300 meters above the ground.

Hope this helped!

Help please! <br>using quadratic formula <br>round ti nearest hundred

Lera25 [3.4K]

Answer:

x = 0.19 or x = -0.76

Step-by-step explanation:

Equation: 7²-4x = 2

reordering the equation,

7x²-4x-2 = 0

Applying,

x = [-b±√(b²-4ac)]/2a..................... Equation 1

From the question,

Given: a = 7, b = -4, c = -2

Substitute these values into equation 1

x = [-4±√(-4²-(2×7×-2)]/(2×7)

x = [-4±√(16+28)]/14

x = (-4±√44)/14

Either

x = (-4+√44)/14

x = (-4+6.63)/14

x = 2.63/14

x = 0.19

x = (-4-√44)/14

x = (-4-6.63)/14

x = -10.63/14

x = -0.76
